The shiftable stop member 95 is connected through an arm 103 thereon andalink 110 to a. bail 107, said bail and stop member being held in normalposition by a. spring 102, which causes the arm 103 to bear against theescepement bracket 33. The stop member 95 is rocked to its double speeefeeding position, (Fig. 6) against the tension of the said spring 102,in the following manner.

Those of the tabuletor stops which are used to stop the carriage atcomputing zones in which it is desirable to skipthe punctuation 5 acesere irovided with extensions 105.

To explain more clearly the double space iiioven'ient's of thetypewriter carriage let it. be assumed that the carriage has reached theten thousand dollars position in an adding.

If we now printinthis position, the escapement mechanismwillkoperete as usual to permitthe carriage to advance a. single letter space distance on tlio returnstroke of the type:

When the (log rocker returns to normalposi-' tion at the rise of the numei'nl key, the loose dog is to theleft or" the adjacent tooth-28 and so engages with the next moth beyond:that, permitting n double space movement of the esoepeinent Wheel beforethe dog 30 is hronght to Test against the stop ll. with the result thatthe carriage is fed two letteri spaces.

To make the double s ence mechanism ineffective, which is desirable whenthe oomputing machine is set to non-edd or disoonnee-t, I have found itadvantageous to pivot n above me :ld key 89,
